Application filed March 24,1905. Serial No. 251,938.

. Type-Writing Machines, of which the followmg is a specificaticinf g My invention relates to type-cleaning devices for type-writing machines, its object being to provide a simple, cheap, and efficient device of the character specified and one which can be readily attached to or detached from a type-writing machine and also secured to the frame of the machine when not in use.

To these and other ends my invention consists of certain novel features of construction, arrangements of parts, and combina-' tions ofdevices, as will be hereinafter fully described, and pointed out in the claims.

In the drawings, in which like reference characters indicate corresponding parts, Figure 1 is a fragmentary perspective view of a number of parts of one character of typewriting machine, illustrating my invention in its a plication thereto. Fig. 2 is a longitudinafsection showing the interior of the easing and the actuating means for operating the brush. Fig. 3 is a section taken on line 3 3' of Fig. 2. Fig. i is a perspective view of the rear wall of thecasing. partly in section, showing an extensible form of device. Fig. 6 is a top view of the same device. 7 is a view showing the improved device stowed in one of the standards of the type-writing frame. Fig. 8 is a sec-- ticnai view showing the device held inside the leg of frame of type-writer by means of an elastic cord and hook and eye.

i have shown my device applied to a Rem ington machine, and sufiicient of such nia-' chine is shown to illustrate my invention in its application thereto.

The frame of the ,machine comprising the corner-posts 1 and top plate 2 has mounted therein by hangers 3 a circular series of typebars 4, which are connected by links 5 to the usual kcy levers. (Not shown.) Extending upwardly from the top plate 2 are risers 6,which support oneof the transverse rods '3, u on which the carriage is supported and guided in its movement from end to end of the machine. v

Connect ed to the shift-rail at its center is a block 12, which. extends downwardly and forwardly from the shift-rail and is providedat its for wardly-projecting portion witha pointer 13, that cooperates with the indices on the usual carriage-scale.

Hrepresents the casing' of the type-cleanin'g device and consists of the circular box,

having a front wall 15 and a rear wall 16. The front wall is usually made integral Withthe circularcasing, while the rear wall is made re- I The casing has an elongated slot 17 in its lower face extending from front to rear. The rear wall 16 of the casing has at its lower edge an angular rearwardlyprojecting tongue 18, which fits within the slot 17 and then extends rearwardly under the cross-bar 14, as shown in Figs. 2 and f6."

To the upper edge of rear wall 16 is a spring latch member 19, extending forwardly over the upper surface of the casing and terminat ing in a downwardlyprojecting lip 20, which fits against the front wall of the casing, thus retaining the rear wall 16 in position and also permitting the same to be readily removed.

'21 is a rod or bar extending forwardly from the front wall of the casing, said bar being i made with a downwardly-offset bend 22 near its front end. The front end 23 is widened and its edge slotted, as at 24, said slot being to brush being rigidly secured to as irallygrooved shaft 26 near one end Said s aft 26 extends through an opening in the-front wall of the casing immediately below the :bar 21 y and into an opening ma de in the downwardlyollset bend. 22, said shaft being also pointed at each end to form p1ntles26.

28 is a nut provided with the curved wings 29 on each side forming linger-pieces. I The nut 28 is grooved or cut out onits upper surface and be guided thereb so that it may slide with. respect to bar 21 Thebore of nut 28 is spirally threaded ano fits snugly on the v As stated before, the brus is rigidly se-' curedto thespirally-grooved shaft 26 near itsend. Now when the nut is moved outwardly it will carry the shaft 26 with it until the front end of said shaft 26 strikes the u turned forward part of the rod. If now t e 1 outward movement of the nut is continued the shaft-will be caused to rotate in one direction and the brush rotates with it, the brush having been carried by the forward movement of the shaft toward the front wall of the casing.

shaft 26 will also be compressed bythis -movement of the nut 28. Now if the forward pressure on the 'nut be released the spring will force the nut rearwardly and cause a reverse revolution of the, shaft and brush and also cause the shaft to move axially rearwardly until the rear pintle end ofthe shaft engages, the rearwall of the casing, said wallforming a bearing for said pintle end of the shaft. It will thus be seen that the brush is revolved alternately in onnosite' cirectio'ns and also has a considerable axial range of movement.

will result in a thorough cleanin -ofboth the upper and lower case ietterson t e-end of the type-bar, which are brought into the slot of' the casing and held there while'b'eing cleaned.

The bar 21 maybe slotted, if desired, and the nut 28 provided with aprojection'fitting in such slotted rod and guidedtherein. The said bar 21.may also be provided with an-extensible attachment 31, as shown in Figs. 5

In applying the device the. (images the type-writing machine is thrown upwardly and backwardly out of the way.

These movements of'the brush, jecting ckwardly and for-' wardly on the guide-rod 21, causing the shaft 26 to rotate and the brush to have a reciprocal rotary movement and also an axial movement, thus perfectly cleaning the type. It

will be observed that one hand is free to manipulate the keys, whilethe other is used to operate the cleaning device.

As shown in Figs. 5- and 6, the extensionpiece 31 may be provided with a slot 32, by means of which and bolt'and nut 33 and 34 it may be moved back and forth upon bar 21. The upper surface of the curved hook 23 is grooved to permit the .backand-forth adjustment of slotted bar 21 and also prevents lateral movement of said slotted bar; but I do not wish to confine myself to such conh struction, as said extension-piece may be made in any practical. manner to fit the-various makes of type-writing machines, and, furthermore, the parts of the improved elean ing device may be so arranged as to permit it to be applied to the rear of atype-writing machine where the peculiar construction of the machine would render its location-necessary at that place.
